Emaginet, Netcentives launch services

Emaginet allows users to select what types of "e-centive" promotions they would like to receive in categories such as computers, travel and automotive.

Sponsors, which have yet to be announced, must buy Emaginet's server for $10,000 and pay a portion of transaction fees. Netcentives declined to disclose details of its network, called ClickRewards, beyond that it plans to emphasize a model such as frequent-flier miles.
